The head of Iran’s Civil Registry says the country’s population growth rate will hit zero in 30 years. Mohammad Nazemi Ardekani said the country then will begin facing a decline in population.

The report established that Iran’s current population is 77.3 million with a fertility rate of 1.7.

Iran implemented a systematic population-control system in recent decades which has been very successful. However, in recent years, the Supreme Leader Ayatollah Khamenei has announced that these control policies were a mistake and the country should in fact try to implement policies to encourage population growth.

Official statistics reveal, however, that most Iranian families prefer to have at most one child.
